Not a coding question... A survey
I'm curious how many people use GalaSoft Mssenger[^] in their apps.
I've always thought that using these types of "relay messaging" tools lead to hard to debug apps and usually indicate some kind of design problem.
Anyone have any thoughts on it?

Message from where to where?
It is a tedious read, and I'm not gonna dig through that entire article to understand what it should do.
If it is inter-app communication, then it is a wrong design. If it is communicating logging to "home", then it might be a privacy-issue.

Yes, it's an inter-app communication thing.
You commented that it's wrong. Please explain why you feel that way.

It is a "GOTO" in disguise; your app send of a WM_MESSAGE and you're off hunting where that is consumed.
Sorry, but the messenger-idea is a solution is search of a problem; there's more efficient ways of inter-app communication, and they have been around for some time.
In the rare case where multiple machines need to communicate over the internet, I'd opt for my own sockets; even XMPP would be preferable to a "new" solution, as it limits my dependencies - there would be enough alternatives if the provider of the solution goes belly up.

I've been working on an app that uses SignalR. Do you think this would be a good way to handle inter-proc commincations?

I can't say, I haven't used it in a real scenario yet.
Their website however states;
ASP.NET SignalR is a new library for ASP.NET developers that makes developing real-time web functionality easy Windows is not a real-time OS. Meaning a library on IIS, piped through ASP.NET, utilizing something else on top of that, is not in my definition of "real time".

There seems to be a misunderstanding from Kevin here. The Messenger implementation of Laurent's is intended for communication inside a single application. It's not inter-app communication.

No, I get it. I've used it in a large scale app before. That's why I mentioned that I thought it could be hard to debug when to classes are firing messages back and forth. I'm just curious about how else this could be done in a simpler manner.

"Inside" the application? A real (desktop) application, or a "webby" or "phoney" app?
Delegates? How about an observer-pattern? Windows messages? Mutexes? Which of those is the library itself using? 
To put it in Garfield-terms; "what's in it for me?", what do I gain by adding the dependency to this library?

Disclaimer: Laurent is a friend of mine, so I might have some bias here.
Messenger/Mediator style communications are perfectly fine because they allow you to separate classes, sometimes over different assemblies, whereby you don't have to know where you're getting a message from, just that at some point, you might (or might not) receive a particular message. This is a perfectly valid way of decoupling classes. What you have to watch out for is something called message explosion, whereby you send everything that you can possibly think of over a messenger. If you're doing that, there should generally be other ways to do this.
BTW - if you're using MVVM Light, that's where the Messenger is.

I've used it before and I do like it. However I found that it leads to hard to debug code, especially if more than one process fires the same message concurrently. I've also seen apps that fire a message from class A to Class B, which then fires another message back to Class A. very hard to follow.
